| dc.description.abstract | The present investigation was undertaken at Breeder Seed Production Centre, GBPUA&T, Pantnagar, Uttarakhand during kharif of 2006-2007. The study was aimed (1) to estimate the genetic variability, heritability and genetic advance, (2) to study phenotypic, genotypic, genotypic and environmental correlation between various characters under study and (3) to estimate direct and indirect effect of various component characters on yield. The observations were recorded on 21 quantitative characters and 16 qualitative characters. The analysis of variance revealed that there is highly significant difference among all 29 treatments for all the characters studied. Genotypic coefficient of variation was the major component of total variation however; PCV was invariably higher than GCV for most of the characters studied. Crude fiber content showed high PCV followed by ear weight, iron content, straw weight and grain yield while plant height showed lowest PCV. Ear weight, straw weight and total biomass showed high heritability and high genetic advance while grain yield exhibited moderate heritability and high genetic advance. Plant height, number of tiller per plant, leaf number per plant and finger number showed low heritability. Finger length, straw weight and total biomass showed highly significant positive correlation with yield. Grain yield was found positively associated with days to 50% flowering, days to maturity, thousand grain weight, ear weight and harvest index. Days to 50% flowering showed highly significant positive correlation with days to maturity, ear weight, straw weight and total biomass. All the nutritional characters were found negatively correlated with yield. Total biomass, harvest index, number of tillers per plant, flag leaf area and days to 50% flowering showed positive direct effect on yield while thousand grain weight showed positive indirect effect on yield through ear weight. In mineral nutrient analysis, it is found that the genotypes namely GE-453, GE-483, GE-2941 and GE-3149 found to contain higher content of manganese than the checks (VL- 146, VL-315). Similarly the genotypes GE-146 and GE-483 were found having higher content of iron while GE-2941, GE-4898, GE-4999 and GE-5230 exhibited more total ash than the checks. However the genotypes viz., GE-2219, GE-2760, GE-3099 and GE-5116 found to contain higher amount of crude fiber over the checks. So, it can be concluded that selection for reduced plant height, more number of tillers per plant, increased ear weight, higher total biomass, greater harvest index and more maturity duration would be in favour of achieving higher yield in the finger millet. | en_US |
